How does that differ from "route it at all"?
Well, locally generated packets are also "routed" onto a local link. While that may not be "routing" in the term's strictest sense, it still is a kind of routing, since it goes through the exact same algorithms. It would also be valid behavior, although probably worthless, to create an IPv6 packet with a routing header, send it to a local router, and make that router route it on to another node on the same link. Therefore, packets with link-local addresses can be routed, but they may not leave the link that they originated from. The distinction is tiny, but it exists.
